Abstract: A method and apparatus for sharpening gastrointestinal (GI) images are disclosed. A target distance between the target region and the imaging apparatus is determined for a target region in the regular image. One or more filter parameters of a de-blurring filter are selected from stored filter parameters according to the target distance. A processed target region is generated by applying the de-blurring filter to the target region to improve sharpness of the target region. A method for characterizing an imaging apparatus is also disclosed. The imaging apparatus is placed under a controlled environment. Test pictures for one or more test patterns are captured at multiple test distances in a range including a focus distance using the imaging apparatus. One or more parameters associated a target point spread function are determined from each test picture for characterizing image formation of the imaging apparatus at the selected distance.

Abstract: An integrated image sensor for capturing a mixed structured-light image and regular image using an integrated image sensor are disclosed. The integrated image sensor comprises a pixel array, one or more output circuits, one or more analog-to-digital converters, and one or more timing and control circuits. The timing and control circuits are arranged to perform a set of actions including capturing a regular image and a structured-light image. According to the present invention, the structured-light image captured before or after the regular image is used to derive depth or shape information for the regular image. An endoscope based on the above integrated image sensor is also disclosed. The endoscope may comprises a capsule housing adapted to be swallowed, where the components of integrated image sensor, a structured light source and anon-structured light source are enclosed and sealed in the capsule housing.

Abstract: A method for determining an object's size based on calibration data is disclosed. The calibration data is measured by capturing images with an image sensor and a lens module, having at least one objective, of the capsule camera at a plurality of object distances and/or back focal distances and deriving from the images characterizing a focus of each objective for at least one color plane. Images of lumen walls of gastrointestinal (GI) tract are captured using the capsule camera. Object distance for at least one region in the current image is estimated based on the camera calibration data and relative sharpness of the current image in at least two color planes. The size of the object is estimated based on the object distance estimated for one or more regions overlapping with an object image of the object and the size of the object image.

Abstract: An in vivo endoscope illuminates tissue using multiple sources. Light from a short-range source exits a tubular wall of the endoscope through a first illumination region that overlaps an imaging region, and the light returns through the imaging region after reflection by tissue, to form an image in a camera. Light from a long-range source exits the tubular wall through a second illumination region that does not overlap the imaging region. The endoscope of some embodiments includes a mirror, and light from an emitter for the short-range source is split and reaches the first illumination region from both sides of an optical axis of the camera. Illuminating the first illumination region with split fractions of light results in greater uniformity of illumination, than illuminating directly with an un-split beam. The energy generated by each source is changed depending on distance of the tissue to be imaged.

Abstract: An in vivo image capturing system includes a capsule, and a camera encased within the capsule and configured to capture through a transparent window of the capsule, a view outside the capsule. The system includes a light source enclosed within the capsule and a reflector configured to reflect a ray of light from the light source, away from the camera. Wherever incoming image rays and outgoing illuminating light rays intersect at a common point on any surface of the transparent window, an angle between an outgoing illuminating light ray and a surface normal exceeds an angle between an incoming image ray and the surface normal such that a reflection of the outgoing illuminating light ray from said any surface is not within a field of view (FOV) of the camera.
